Methanol → 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methylquinolin-2(1H)-one hydrochloride

Participants

Reaction Steps

To 2.0 mL of a methanol solution containing 0.25 g of tert-butyl (2,3-dihydro-1,4-benzodioxin-6-ylmethyl)(1-(2-(7-methyl-2-oxoquinolin-1(2H)-yl)ethyl)piperidin-4-yl)carbamate, 2.0 mL of 4 mol/L hydrogen chloride/ethyl acetate solution was added and stirred for 30 min. Ethyl acetate was added, and the resulting solid was filtered to afford 0.18 g of 1-(2-(4-((2,3-dihydro-1,4-benzodioxin-6-ylmethyl)amino)piperidin-1-yl)ethyl)-7-methylquinolin-2(1H)-one hydrochloride as a white solid.
